Imaging findings
This patient demonstrates bilateral superior vena cava (SVC) without a bridging innominate vein. Unusually, the left SVC drains entirely into the superior intercostal vein, which then courses into the azygos vein before ultimately connecting to the right SVC.
Key takeaways
Bilateral superior vena cava is a congenital venous anomaly, with varying drainage patterns for the left SVC. This case illustrates a unique pathway where the left SVC connects to the azygos system via the superior intercostal vein. Identifying such variants is important for surgical and interventional planning to prevent complications.
